METALLIC SEAL.

SPECIFICATION forming part of Letters Patent No. 368,126, dated August9, 1887.

Application ltiled June 29, 1857.

To all whom t may concern:

Be it known that I, EDWARD J. BROOKS, a citizen of the United States,residing at East Orange, in the State o'f New Jersey, have invented anew and useful Improvement in Metallic Seals, of which the followingis aspecicationl This invention relates to those seals in which a soft-metalseal-disk, lcommonly lof lead, is combined with a shackle of flexiblewire, and it is primarily additional to my improvement in metallic sealspatented March 4, 1884, (United States Patent N o. 294,576,) whichcomprises leadand-wire seals in which thefree ends ofthe wires, (as theyare hereinafter commonly termed,) in the form of loops, are received byrecesses in the faces of the seal-disks,

so as to protect lthe loop against being tam- The primary object of thepresent invention is to adapt such seal-disks to so receivel and toseeurelyso fasten both' ends of the wire, whereby the seal-disks may bemore cheaply cast and may be used in connectionwith ordinary commercialwire, or wire of any preferred style, furnished in straight lengths andbent as required by the scalers.

Another object of this invention is to facilitate forming as well 'asintroducing the loop at the sealing operation, whether the wires haveone or two free ends, and by the same means to render the seal,especially if of large size, more secure at the open edge of theseal-disk.

The-invention consists in certain novel combinations of parts,depending, respectively, uponthe peculiar construction of the seal-disk,as hereinafter set forth and claimed.

A sheetof drawings 'accompanies this speciiication as part thereof.

Fig. 9 represents a sectional face view of a similarseal-disk cast on one end ofthe wire. Fig. 10 is a perspective vie-W ofa seal disk, illustrating another modification. Fig. l1 is a face -viewof the same combined with a loose wire and ready for the press. Fig. 12is a face view of a similar seal-disk cast on one end of the wire. Fig.13 represents three illustrative formations of the cast-in end of thewires represented in Figs. 6, 9, and 12. Fig. 14 represents asmallhorseshoe seal-disk and a ready-bent wire for use therewith, and Fig. 15represents a longitudinal section of the same as combined and ready forthe press.

Likeletters of referenceindicate correspond ing parts in all thefigures.

Each of the several metallic seals represented by the drawings iscomposed of a horseshoe seal-disk, A, A2, A, At, A5, A, or A7, and ashackle or wire, B, B2, B, B,

B5, B, or Bl, the free end or each free end of i the-wire being bentinto a loop, a, of horseshoe shape,at or before the sealing operation,and received in this shape by a recess, b, of the same or approximatelythe same shape,in the face of the sealdisk, within which the loopembraces acentral post, c, which must be cut through if the loop bewithdrawn, while solid edge walls d keep the loop from opening underlengthwise strain, and the recess locates its main bend so far withinthe disk as to prevent access thereto.

In the seal represented by Figs. 1 to 5, inelusive, which embodies allthe several parts of the present invention, the seal-disk A contains arecess b of sufficient depth to receive loops cc on both ends of thewire R, one over or upon the other, and to insure turning in the deepedge wall l at every point the edges c of the disk, excepting its top7f, are beveled from back to front, as best seen in Fig. 4. Thesefeatures of this seal are common to it and those seals with loose wiresrepresented by Figs. 10, 11, 14, and15, as indicated by correspondingreference-letters. Referring again to Figs. 1 to 5, it will be seen thatthe topfof said seal-disk A is provided with a pair of apertures, g,which communicate with the respective upper ends of the recess b, sothat each free end of the wire B may be threaded obliquely through oneaperture, as illustrated at the lefthand side of the seal in Fig. 3, andthen back through the other aperture, as represented by dotted lines, soas to complete the loop thereof by pulling the wire endwise. Uponreaching the required size the loop a is instantly pressed into therecess b by the thumb of the hand which grasps the scaldisk. Thisfeature is common to all the seals represented by the drawings, saveonly that one represented by Figs. 111 and 15. Referring again to saidFigs. 1 to 5, itwill be seen that said ap ertures g, in the form ofholes, penetrate an otherwise solid upper end of the disk which unitesthe ends of its side walls, 7., so as to preclude bending them apart.This construction materially increases the security of the seal,especially when made of large size. It also further facilitates formingthe loops as aforesaid. It is common to this seal and those representedby Figs. 6, 7, S, and 9. Referring once more to said Figs. 11o 5,it willbe observed that said edge walls d and beveled edges c extendcontinuously around the bottom as well as at the lateral edges of thesealdisk, so as to preclude edgewise access to the loop within theseal-disk at all points. This construction is preferred and is common toall the seals represented by the drawings, except those represented byFigs. 7, 8, and 9.

The modified seal represented by Fig. Gis identical with said sealrepresented by Figs. 1 to 5,except that its seal-disk A is cast fast onone end of the wire Bi, so that its recess b, post c, edge walls d,beveled edge c, top f,and apertures g aid in securing the other endonly.

The modified sealdisks Aand A ofthe seals represented by Figs. 7, 8, and9 are designed to be cast in simpler molds, with that part which formsthe recess I removable endwise. They consequently have open lower ends,to compensate for which the post c is undercut, as indicated by dottedlines in Fig.l 7 and clearly shown in Figs. S and 9. The loop a is drawnup around the contracted shank ofthe post, and when the seal is pressedthe post itself more securely envelops the main bend of the loop, so asto prevent access to it.

The modified seal-disks A and AG ofthe seals represented by Figs. 10,1l, and l2 are identical with said seal-disks A and A2, save only thattheir apertures g are open in front, so that they, as well as the recessb, may be formed by a mold part withdrawn perpendiculariy to the face ofthe disk. Consequently these apertures would have to be guarded at theface of the seal by the thumb of the hand which grasps the seal-disk informing the loops by rethrcading and pulling the wire in the manneraforesaid.

The wires B and B"l may be identical with said wire B. Like said wireBi, the wires B* and 3 are each cast in 7 at one end, as aforesaid. Thecast-iu ends of these wires may be anchored in any approved way. Forexample, asillustratcd by Fig. 13, either of them maybe anchored withinthe seal-disk by means of a loop, h, as set forth in my patent, No.154,639, dated September l, 1874, 0r by indentations i, as set forth inmy patent, No. 179,260, dated J n ne 27, 187 6, or by one or moreenlargements, 7c, as set forth in my patent, No. 192,735, dated July 3,1877. These examples may suffice.

The small seal represented by Figs. 14. and 15 has a single aperture,g', in the topf of its sealdisk Al, which is thus and otherwise adaptedto coact with ready-formed loops a at both extremities of its wire B7.

Other like modifications will suggest themselves to those skilled in theart. I propose, for example, to use in connection with either of theaforesaid seal-disks any of my patented wires which may be suitable; andthe seal-disks maybe round or of other shapes externally, if preferred.

To facilitate carrying and applying those seals which have loose wires,one end of' the wire may be prelimi narily united with thcsealdisk inthe manner aforesaid, as illustrated at the righthand side in Fig. 3.The seals are applied to car-door staples C, or the like, in customarymanner, and after forming and introducing the last of their loops, asaforesaid, are fastened by means of a suitable sealpress, whichsolidifies the seal-disk around the loops. The previously open face ofthe seal-disk is thus closed up in front of the loops, as represented inFig. 5, and is guarded against being tampered with by the press-marks m,which are formed upon or in the same, and may be of any approvedcharacter.

Having thus described my said im provelnentin metallic seals, I claim asmy invention and desire to patent under this specificationl. Thecombination, in a metallic seal, of a loose shackle-wire having a loopat each end, a seal-disk having a recess in its face which receives saidloops one over or upon the other, a central post within the loops, edgewalls around the same, and a beveled edge, substantially as hereinspecified.

2. The combination,with a suitable shackle wire, of a seal-disk having arecess in its face, a central post, edge walls, a solid upper enduniting said walls at this point, and a pair of apertures in the top ofthe seal-disk communieating with said recess on the respective sides ofsaid post, substantially as herein specified, for the purpose set forth.
